摘要： A pneumatic tire with tread, beads and sidewalls in which each bead is provided with a rubber apex of rubber compound of hardness at least 60*BS extending into the lower sidewall region of the tire and a reinforced strip extending around the bead and into the lower sidewall region of the tire both axially inwardly and axially outwardly of the tire. Together the reinforced strip and the rubber apex form a cantilever lower sidewall construction, the ratio of the overall internal width of the tire to the distance between the axially outermost tire contacting points on the wheel rim being in the range 125 to 200 percent, of which the following is a specification.
